It has a dedicated shortcut to the Windows 8 start screen, and uses Logitech’s Unifying Receiver; battery life is up to six months with two AA batteries, or you can ditch one of the batteries for a lighter mouse, and get up to three months runtime.

As for the Zone Touch Mouse T400, as the name implies the touch-responsiveness is limited to certain portions of the peripheral. In fact, the zone is limited to where the scroll-wheel might normally be expected to find, with a rubberized, textured surface. The same Unifying Receiver is used, and battery life is up to 18 months.

Like Apple’s Magic Trackpad of 2010, Logitech’s Touchpad T650 pulls the touch-sensitive square normally found in a laptop’s wrist rest out onto the desktop as a standalone peripheral. It supports thirteen Windows 8 gestures, and can be recharged via USB; a full charge is good for up to a month’s use.
